Fishing Diver Dual Tripping Device Friction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing divers with tripping devices face issues of premature release due to improper frictional retaining force settings, leading to line breakage and missed catches, especially when fishing for smaller fish, as they either trip prematurely or fail to release when a fish is caught.
Innovation Solution
The introduction of dual tripping devices with separate force adjusting mechanisms and a deformable sleeve to minimize line contact with the eyelet, allowing for adjustable frictional retention and reduced line breakage, ensuring accurate fish detection and release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the frictional retaining force on the latch arm is set too light, then the diver may trip prematurely before a fish is caught, but if set too high, then smaller fish may be caught and dragged along indefinitely without reaching the released condition
Solution Approach 1:
The patent divides the single tripping function into two separate tripping structures (first and second tripping structures), each with independent force adjusting screws. This segmentation allows different frictional retaining forces to be optimized for different fish sizes, resolving the contradiction between reliable latch release and adaptability to various fish sizes.
Solution Approach 2:
The patent introduces adjustable force adjusting screws that allow the frictional retaining force to be dynamically changed based on fishing conditions and target fish size. This dynamic adjustment capability enables the same diver to reliably trip for both small and large fish, resolving the adaptability issue.
2Device complexity
If a single tripping device is used, then the device complexity is reduced, but the ability to handle different fishing scenarios and fish sizes is compromised
Solution Approach 1:
The patent segments the tripping function into two coordinated structures working together as an integrated system. While the number of components increases, they function as a unified mechanism that provides enhanced adaptability without requiring multiple separate devices, thus balancing complexity and versatility.
Solution Approach 2:
The dual tripping structure system serves multiple functions: it can be adjusted for different fish sizes, different trolling speeds, and different water conditions. This multi-functionality compensates for the increased complexity by providing a single versatile system rather than multiple specialized devices.
3Device complexity
If the line contacts the eyelet directly, then the device structure is simpler, but line breakage risk increases
Solution Approach 1:
The patent introduces a deformable sleeve as an intermediary component between the line and the eyelet. This sleeve distributes the contact pressure and prevents direct line-to-eyelet contact, reducing line breakage risk. The added component is justified by the significant improvement in line reliability it provides.
Solution Approach 2:
The deformable sleeve is a flexible protective component that conforms to the eyelet shape while protecting the line. This flexible shell approach provides effective line protection without adding significant structural complexity, as the sleeve is a simple deformable component rather than a rigid structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual tripping device system with adjustable frictional forces and a deformable sleeve enhances fishing efficiency by minimizing line breakage and ensuring that fish are detected and released correctly, preventing both premature release and dragging of fish along the lure.
Implementation Method 1
A protective sleeve in the form of an elongated coil spring encircles the line and extends rearwardly of the front tab, and then through and beyond the eyelet such that an inside surface of the spring provides an increase surface for the line in the vicinity of the eyelet whereby to minimize the line breakage
Implementation Method 2
The latch arm in the latched condition is pivoted rearwardly and frictionally held by gripper jaws along a central portion of the latch arm between the eyelet end and the pivotally mounted end. A screw passes through the gripper jaws to adjust the frictional retaining force of the latch arm in the jaws in the latched condition

AI summary
A fishing diver is provided by a diving plane with a first releasable tripping device having a latched condition clamping the diving plane to the line such that upon trolling, the diver dives downwardly at an angle to the trolling line, and having a released condition unclamping the diving plane from the line. The diver includes a second tripping device associated with and engageable with the releasable first tripping device. The second tripping device has a latched condition engageable with the fishing line, and a released condition responsive to the strike of the fish on the lure for causing the first tripping device to reach its released condition and provides free sliding passage of the line through a guide structure on the diving plane.
